Colombo "unlikely" to agree to China's request: Sri Lankan official

China says it needed a place for submarines used for anti-piracy missions

China defended its military relationship with Sri Lanka as good for regional peace and stability after Sri Lanka rejected a request from China to dock one of its submarines in Colombo this month. Sri Lanka's decision was announced as Prime Minister Narendra Modi arrived on the island nation for an overnight trip.

Sri Lanka last allowed a Chinese submarine to dock in the capital of Colombo in October 2014, a move that triggered fierce opposition from India, which worries about growing Chinese activity in a country it has long viewed as part of its area of influence.

The timing of the incident is awkward as Sri Lankan Prime Minister Ranil Wickremesinghe is expected in Beijing this weekend to attend a summit on China's new Silk Road plan.

China's Defence Ministry, in a statement sent to Reuters, did not directly mention the rejected request for the submarine visit, but said its submarines needed a place to resupply on their way to anti-piracy missions.

"The stopping to resupply of our military's submarines that are on their way to the Gulf of Aden and Somali waters for protection missions is an internationally accepted practice," the ministry said.

In recent years, the Chinese and Sri Lankan militaries had fruitful and effective cooperation in areas like mutual visits and training, it added.

"The cooperation between the Chinese and Sri Lankan militaries is beneficial to regional peace and stability, is not aimed at any third party and should not be interfered in by a third party," the ministry said, without elaborating.

According to news agency Reuters, a senior Sri Lankan government official said China's request to dock one of its submarines in Colombo this month had been rejected. He said Sri Lanka was "unlikely" to agree to China's request to dock the submarine at any time, given India's concerns.

A second official, at the defence ministry, also said China's request to dock this month had been rejected but that a decision on a further docking had been postponed.

A 1987 accord between India and Sri Lanka provides that their territories not be used for activities deemed prejudicial to each other's unity, integrity and security.

China has invested heavily in Sri Lanka in recent years, funding airports, roads, railways and ports, unsettling India, traditionally the closest economic partner of the island nation of 21 million people.
